The Choppiness Index is designed to determine whether the market is choppy or trading sideways, or not choppy and trading within a trend in either direction. Using a scale from 1 - 100, the market is considered to be choppy as values near 100 (over 61.80) and trending when values are lower than 38.20).

Double exponential moving averages (DEMA) are an improvement over Exponential Moving Average (EMA) because they allocate more weight to recent data points. The reduced lag results in a more responsive moving average, which helps short-term traders spot trend reversals quickly.

Currently implemented for MT4. Some uses for ER: - A qualifier for a trend following trade; a trend is considered "persistent" only when RE is above a certain value, e.g. 0.3 or 0.4 . - A filter to screen out choppy stocks/markets, where breakouts are frequently "fakeouts". - In an adaptive trading system, helping to determine whether to apply a trend following algorithm or a mean reversion algorithm. - It is used in the calculation of Kaufman's Adaptive Moving Average (KAMA).
